(meteorobs) April 9, 2003 Meteor Observations from California
I spent an enjoyable three hours under the stars this morning. Meteor
activity
was low but consistent throughout the session. Nineteen of the twenty
meteors
seen this morning were sporadic. The only shower member was a +4 antihelion
meteor seen at 3:55 local daylight time. There was no truly notable meteors
seen
during the session. The highlight was probably the -4 iridium flare that
occurred
during the last hour.
